Abstract

The invention relates to a device for eliminating rail gnawing of a trolley of a large-size bridge crane. An additional disc spring supporting arm is arranged at the bottom of an existing trolley of the bridge crane. The device comprises a main body frame, the disc spring supporting arms, rolling balls and disc springs; a disc spring shell is installed on the periphery of each disc spring; the main body frame is fixedly connected with a crane trolley bottom connector; the two ends of the crane trolley bottom connector are provided with trolley wheels; the trolley wheels are arranged on trolley rails which are arranged on girders of the bridge crane; the two disc spring supporting arms are fixedly arranged on the two horizontal sides of the lower end of the main body frame; each rolling ball is installed at the end of the corresponding disc spring supporting arm; and a circular-groove-shaped guide rail is arranged between each rolling ball and the corresponding girder of the bridge crane. The device for eliminating rail gnawing of the trolley of the large-size bridge crane has the beneficial effects that the structure is simple, and operation is stable; and fraction and rail gnawing between the trolley wheels and the guide rails is eliminated, meanwhile, serious potential safety hazards cased by rail gnawing of the trolley is eliminated, and the safety of operation of the device and the personnel security are effectively ensured.

Description

technical field [0001] The invention relates to a disc spring support arm, which can adjust the running state of a crane trolley and eliminate rail gnawing by the trolley. Background technique [0002] The ideal operating condition of the crane should be that all the wheels roll on the track without slipping, and the wheel rim does not touch the track it is running on, that is, a certain gap is maintained between the wheel rim and the wheel track. But in fact, for some reason, when the crane was running, the rim of the wheel came into contact with the rail forcibly, causing rail gnawing. At present, the methods to eliminate the rail gnawing of the crane trolley in China are to check the track, replace the wheels, and repair the gauge of the trolley. During the hoisting process of the crane, there will be reasoning in the horizontal direction. Over time, this kind of rail gnawing will happen repeatedly, and the problem cannot be solved fundamentally. [0003] For this reaso...
